MANUFACTURING PROCESSES - FIT

Manufacturing metal mold is much more expensive than manufacturing sand molds or investment casting process mold. Minimum number of castings for profitable use of a permanent mold is dependent on the complexity of its shape. Ferrous and no-ferrous metals and alloys are cast by the permanent mold casting process.

Metal Casting Methods: Life of a Casting | Reliance Foundry

Sand casting is the most common method used for metal casting. It is manufacturing process at least three thousand years old: the first evidence of clay casting comes out of China, during the Shang Dynasty (c. 1600 to 1046 BC). It is no wonder this process is still so popular: sand is cheap, plentiful, pliable, and able to take the heat.
